Rethinking practitioner roles in chronic illness: the specialist, primary care physician, and the practice nurse

Abstract

In this article, we describe an evidence-based stepped care approach to improving the care of chronic illness in organized health care systems. We review the common principles that have been found to improve the management and outcomes of patients with major depression, asthma, diabetes, and congestive heart failure. These population-based methods to improve care of chronic illness require reorganizing the roles of specialists, primary care physicians, and nurses.
